THREAD-GUIDE SUPPORT FOR SPINNING 0R TWISTING MACHINE S.

SPECIFIGATIQN forming part of Letters Patent N 0. 677,988, dated July 9, 1901.

Application filed Deceniber I0, 1900. Serial No. 39.278. (No model.) d

To all whom it may concern:

Be it known that I, LEWIS T. HoUGHToN, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented a new. and useful Thread-Guide Support for Spin ning or Twisting Machinery, of which the following is a specification.

This invention relates to an improved construction for supporting the thread-guides of a spinning or twisting machine; and the object of this invention is to provide a lighter, stronger, more durable, and simpler support for such thread-guides than has heretofore been used.

The thread-guide support forming the subject-matter of this invention is preferably stamped out of sheet metal and is designed to form an efficient cover for preventing loose ends of thread or other matter from falling down, so as to become snarled with the drivingbands of the spindles, which will also have a smooth uninterrupted surface, which may be readily wiped, so as to prevent dirt or dust from accumulating thereon.

To accomplish these ends, this invention consists of the parts and combinations of parts, as hereinafter described, and more particularly pointed out in the claims at the end of this specification.

In the accompanying drawings, Figure 1 isa perspective view illustrating theapplication of a thread-guide constructed according to this invention to the frame of a spinning machines wooden finger-heads are employed,

into which the thread-guides are directly threaded or driven. In some of the latter forms of spinning and twisting machines metallic constructions have been employed for supporting the thread-guides; but all of such constructions with which I am familiar are comparativelycomplicated and expensive and in practical useare liable to become broken and deranged.

The especial object of my present invention is therefore to provide a support for the thread-guides of a spinning or twisting machine which will consist of the least possible number of pieces and the parts of which are preferably stamped up out of sheet metal, so that the same will form a very strong substantial construction which may be readily applied to the ordinary forms of spinning or twisting machines.

Referring to the accompanying drawings and in detail, A designates a portion of the side bar or framework of any of the ordinary spinning or twisting machines, and secured to the framework A is athread-guide sup The thread-guide support as herein illustrated preferably comprises a finger-head board and a number of finger-heads connected thereto byhinged joints, formed by parts which are integral with the finger-head board and finger-heads, respectively. The fingerhead board 10 preferably consists of a coma rearflange 13. At one or more places along its rear edge the finger-head board 10 is pro vided with integral rolled or turned up portions 14, which codperate with a plate or butt 15 to form a hinge for connecting the fingerhead board to the frame A. The finger-head board may, if desired, be formed of one continuous piece extending the entire length 'of the machine, although in practice it is preferred to make the same in several separate lengths, which may be left independent or may be connected at the ends by screws, as illustrated in Fig. 2. Eachof the finger-heads 11, which are supported by the finger-head board, consists of a sheet-metal body portion having end flanges 27. The finger-head 11 is provided at its rear edge with integral turned or rolled up sections 16, which are arranged to. intermesh with turned or rolled up sections 17, formed integrally with the finger-head paratively long sheet-metal body portion hav- 'ing integral turned-down end flanges 12 and board to constitute the hinge-joint which connects said parts. The side flanges 27 of the finger-head 11 are arranged to extend back under the finger-head board 10 to form stops for holding the finger-head in position when the same is turned down, as shown.

Any desired form of clamping mechanism may be used for clamping a thread-guide to the under side of the finger-head, although in practice I prefer to employ a clamping mechanism which will permit a swinging and inand-out adjustment of the thread-guide and which will leave the upper surface of the fin-- the finger-head forming stops for holding the ger-head substantially uninterrupted.

As shown in Figs. 1 and 3, a thread-guide may be adjustably clamped to the under side of the finger-head by means of a screw 18, which is threaded into a grooved clamp or holder 19. In some cases instead of employing this form of clamping mechanism I mayemploya U-shaped clamping-bolt 21 for engaging the shank of the thread-guide,which may be held in place by a nut 22, as illustrated in Fig. 4.

In a thread guide support as thus constructed it will be seen that the finger-head board and finger head are directly hinged togetherthat is to say, the sections forming the hinge-joint between these parts are formed integrally therewith-and although I prefer to form this hinge -joint by integral intermeshing turned or rolled up sections on said parts other means may be provided for forming such direct hinge-joint.

I am aware that other changes may be made in the construction of my thread=guide for spinning or twisting machines, and I do not wish, therefore to be limited to the construction which I have herein shown and described; but

What I do claim, and desire to secure by Letters Patent of the United States, is

1. In a support for a thread-guide of a spinning or twisting machine, the combination of a sheet-metal strip or finger-head board, and a finger-head having top and side flanges stamped from a single piece of sheet metal, and having integral sections at its rear edge bent or turned to form a socket for receiving the hinge-pin which connects the finger-head to the finger-head board, the side flanges of finger-head substantially horizontal when the same is in its turned-down position, substantially as described.

2. In a support for a thread-guide of a spinning or twisting machine, the combination of a sheet-metal strip or finger-head board, and a sheet-metal finger-head having the top and side flanges stamped from a single piece of sheet metal, and having integral sections at its rear edge bent and rolled up to form a socket for receiving the hinge-pin which connects the finger-head to the finger head board, and constructed so that the side flanges extend back beyond the hinge-pin socket so as to form stops for supporting the finger-head, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
